3. Net the items of income, loss or deduction, after the calculation under subd.
2., for all of the days during which the partner or member was a resident of this state.
71.04(3)(b)

All partners or members who are residents of this state for less than a full taxable year or who are nonresidents shall compute taxes for that year on their share of partnership or limited liability company income or loss under this chapter for the part of the taxable year during which they are nonresidents by recognizing their proportionate share of all items of income, loss or deduction attributable to a business in, services performed in, or rental of property in, this state.

(c)

71.04(3)(c)3.
3. Allocate to a partner or member a greater proportion of a partnership or limited liability company item of loss or deduction from sources in this state than the partner's or member's proportionate share of total partnership or company loss or deduction.

Nonresident allocation and apportionment formula. Nonresident individuals and nonresident estates and trusts engaged in business within and without the state shall be taxed only on such income as is derived from business transacted and property located within the state. The amount of such income attributable to Wisconsin may be determined by an allocation and separate accounting thereof, when the business of such nonresident individual or nonresident estate or trust within the state is not an integral part of a unitary business, but the department of revenue may permit an allocation and separate accounting in any case in which it is satisfied that the use of such method will properly reflect the income taxable by this state. In all cases in which allocation and separate accounting is not permissible, the determination shall be made in the following manner: for all businesses except air carriers, financial organizations, telecommunications companies, pipeline companies, public utilities, railroads, and car line companies there shall first be deducted from the total net income of the taxpayer the part thereof (less related expenses, if any) that follows the situs of the property or the residence of the recipient. The remaining net income shall be apportioned to this state by use of the following:
